5.12

eko vaśī sarvabhūtāntarātmā ekaṃ rūpaṃ bahudhā yaḥ karoti /
tam ātmasthaṃ ye 'nupaśyanti dhīrās teṣāṃ sukhaṃ śāśvataṃ netareṣām //

12. The Inner Soul (_antarātman_) of all things, the One Controller,
Who makes his one form manifold—
The wise who perceive Him as standing in oneself,
They, and no others, have eternal happiness!
13. Him who is the constant among the inconstant, the intelligent
among intelligences,
The One among many, who grants desires—
